Corrosion of third degree of left toe(s) (nail), sequela

This code signifies a third-degree burn on the left toe(s) or toenail, specifically caused by corrosive substances. A third-degree burn involves full-thickness skin destruction, extending into subcutaneous tissue, and is characterized by a leathery, waxy, or charred appearance. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial corrosive burn, after the acute phase has passed.

Use this code when documenting long-term effects, complications, or ongoing treatment related to a past third-degree corrosive burn of the left toe(s) or toenail. This could include chronic pain, scarring, contractures, non-healing ulcers, or other persistent issues directly attributable to the original injury. It is not for the initial acute injury.

• Always sequence this code after the code for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a previous third-degree corrosive burn of the left toe(s).
• Verify the burn was indeed third-degree and caused by corrosion, not other burn types.
